Why Is the Sky Blue?: The World According to Grandpa, Book 1 (Unabridged‪)‬

Stanley's grandpa knows absolutely everything about everything. Whatever you ask him, he always seems to know the answer. But a little-known fact about every granddad in the world is that when they don't know the answer to your question, they make something up out of thin air. It may be a load of utter hogwash, but it's always entertaining. Why Is The Sky Blue? is the very first story in The World According To Grandpa series.
